. MILITARY," SHOULDER-ARM.

To all whom'z'tmay/ concern: p f y Be it known that I, THOMAS C.JOHNSON, a citizen of the United States, residing; at New Haven, inthecounty -of New Haven and Statepof Connecticut,have invented a new anduseful Improvement in Military Shoulder-Arms; and I do hereby' declareYthe, following, when'ftakenin connectionk with the accompanying drawingsandthe characters of reference marked thereon, to

be a full, clear, and eXact description of the same, and which saiddrawings constitutey part of this application and represent, in

Figure 1 ar view partly in section, and

partly in right hand side elevation of the middle portion of a militaryshoulder-arm constructed in accordance with my invention. Fig. 2 abroken reverse `plan view thereof. Fig. 3 a broken plan view of therearend of the rforestock. Fig. l a detached side view of the forearmtie-piece. Fig. 5 a detached view in front elevation of thereceiver-extension. Fig. k6 a View in rear elevation of the forestock.

. My invention relates to an improvement in military shoulder-arms, theobject being to provide simple and reliable means for holding theforestock against forward displacement without imposing any strain uponthe barrel of the arm.

With these ends in view, my invention consists ina military shoulder-armhaving certain details of construction as will be hereinafter describedand pointed out in the claims.

In carrying `out my invention as herein shown, I employ a forestocktie-piece consisting of a shank 2 formed at its forward end with` adepending wedge-like locking lug 3 having a rounded forward face l andabeveled rear face 5, and adapted to be entered into a verticallocking-recess 6 of cory responding form, leading downward out of thebottom of theforward end of a longitudinal clearance groove 7 Vformed inthe 4'upper face of the rear end of the forestock 8. At its rear end,the said shank 2 is provided with a threaded stem 9 which is yscrewedinto a threaded ybore formed in a order to increase the length of thelockinglug 3 and hence enlarge its hold upon the beveled rear yface 5 ofthe locking-recess 6 Specification of Letters Patent.y

, plainly shown in Figs. 1 and Ll, whereby the forward end of the saidshank is made to some extent iexible. yNow to prevent it from verticaldisplacement atits forward end, its locking-lug''is 'formed' with avertical, threaded bore 14 for the reception of the upper end of a screwl15 which draws the wedge-like locking-'lug 3 downsnugly into itslocking position in the locking-recess 6. The outer end of the screw 15is entered into a shouldered bushing or es- `cutclieon 16 flushed into ashouldered chamber 17 formed in the lower face o f the fore- -stock inline with the recess 6 the bottom of which it intersects.

The receiver-extension 12 is formed with a threaded opening receivingthe shank 18 of the gun-barrel 19, from which the forestock ispreferably cleared by a space 20. The forward face of thereceiver-extension n contains a shallow recess 21 for the recepforestooktie-piece 2 firmly `holds the fore-l c stockagainst forward longitudinaldisplacement.

term receiveimin the claims is to be under- So far as my presentinvention is` concerned,the receiver-extension 12 mightl be madeintegral with the receiver 13. The

stood as covering the receiver, whether its extension lis integral orotherwise, except in lthose claims in which the receiver-extension isspecilically mentioned.`

I claim 1. In a military shouldenarm, the combination with lthe receiverthereof, of a forestock formed in the upper face of its rear -end with alongitudinal clearance groove having a vertical locking-recess leadingdownward from its forwardy end, a forestocktie-piece located inthesaidlongitu `dinal groove'and formed at its forward end with a locking-lugentering the said recess and connection at itsvrear end with ythereceiver, and a screw passing upward through the forestock and into thesaid lug for seating the same firmly in the said recess.
